GPO's Federal Digital System (FDsys) is an advanced digital system that will enable GPO to manage Government information from all three branches of the U.S. Government.

FDsys is available as a public beta during migration of information from GPO Access. The migration of information from GPO Access into FDsys will be complete in 2009, until this time GPO Access will contain all content.

Some of the main functions of the system include:

Publishing
The U.S. Congress and Federal agencies will be able to submit files and orders electronically to GPO for printing and publishing services, electronic distribution, and inclusion in the Federal Depository Library Program (FDLP)

Searching for information
Government information will reach a wider audience by providing authentic; published Government information to the public through an internet based system

Preserving information
The preservation function of FDsys will ensure public access to government information even as technology changes

Version control
Multiple versions of published information are common; FDsys will provide version control for government information.
